EMF/RFI shielding isn't as important for active pickups as it is for passive ones, but I did this before I decided to upgrade the pickups. Plus, I believe that all pickup cavities on all electric guitars should be shielded.

'96 Ibanez Talman

This is a '96 Ibanez that got it's frets leveled, crowned, and pollished along with a new handmade bone nut and reconditioned fretboard. All hardware was cleaned, polished, and lubed (where applicable). I used copper conductive paint to shield the pickup and control cavities and a coper sheeet on the pickguard. New EMG passive humbuckers with chrome covers were made to order. It had problems with tuning due to a bad nut and the owner considered going to a hardtail bridge, but with freshly lubed tuners and a properly made nut, I'll be setting the bridge up fully floating. It now sounds great and plays very nicely, too, with stable tuning. Knob for 3-way switch is on order.
